Go 6983 is a protein kinase C (PKC) inhibitor with IC50 values of 7 nM, 7 nM, 6 nM, 10 nM and 60 nM for PKCα, PKCβ, PKCγ, PKCδ and PKCζ respectively. Go 6983 inhibited intracellular Ca(2+) accumulation, suggesting a mechanism for its vasodilator properties. In vitro, Go 6983 significantly inhibited antigen-induced superoxide release from leukocytes of patients previously sensitized to tree pollen. Go 6983 (100 nM) significantly reduced PMN adherence to the endothelium and infiltration into the myocardium compared with I/R + PMN hearts (P < 0.01), and significantly inhibited superoxide release from PMNs by 90 +/- 2% (P < 0.01). Go 6983 attenuated post-I/R cardiac contractile dysfunction, which may be related in part to decreased superoxide production in the presence of PMNs.

| Cell Lines | Tca8113 cells | |
| Concentrations | 5 μM | |

| Results | As shown in Fig. 4, after PKD2 was inhibited by Gö6983, IFN-γ could not induce the surface expression of PD-L1 on Tca8113. |
| Molecular Weight | 442.51 |
| Formula | C26H26N4O3 |
| CAS Number | 133053-19-7 |
| Solubility (25°C) | DMSO ≥ 30 mg/mL |
| Storage |
Powder -20°C 3 years ; 4°C 2 years In solvent -80°C 6 months ; -20°C 1 month |
| Species | Mouse | Rat | Rabbit | Guinea pig | Hamster | Dog |
| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
